Specification of Letters Patent. Patented Feb. 14 1922.

Application led August 17, 1918. Serial No. 250,267.

To all whom it may concern.'

Be it known that I, MATTHIAS BROCK, a citizen of the United States, residin at Boston, in the county of Suffolk and tate of Massachusetts, have invented certain lmprovements in the Art of Making Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

.This invention relates to the art of making shoes and more specifically to the earlier stages in the process of the manufacture of a shoe during which the upper is both given the shape of the last upon which the shoe is largely manufactured and is also secu red to the insole.

Although the invention may be utilized in the manufacture of various types of shoes, which term is herein intended to include boots, slippers and other footwear, it is herein described particularly with reference to the manufacture of Goodyear welt shoes which, according to the prevailing practice, remain upon the last throughout substantially the entire bottoming operation. More specifically, in making a Goodyear welt shoe, an insole is usually tacked to the bottom of the last and then the upper, including the lining and end stiffeners, is assembled upon the last and the upper is pulled over and lasted, thereby' imparting to the shoe the shape of the last and, indeed, the shape -which the finished shoe is to have. After this shaping, the bottoming of the shoe proceeds.

While, on the one hand, the superior appearance and fit of a Goodyear welt shoe is largely due to the fact that the last remains continuously therein from the time when it is first inserted until the shoe is virtually completed, yet, on the other hand, the direct and indirect expense of providing and maintaining a full equipment of lasts is an increasingly heavy burden for the shoe manufacturer.- Hence, it is a primary object of the present invention to reduce the number of operations in the manufacture of a Shoe which are performed while it is mounted on the last and, in general, to increase the oliiciency of the process of making a shoe.

Accordingly, a very important feature of the present invention is that the upper and insole, or it may be the sole of a single soled shoe, are secured together before they are assembled upon the last. rllhus, the invention, 1n one aspect, comprises securing off the last a relatively small section of an upper tol a sole, whether it be an insole or a turn sole, thereafter mounting the upper and sole thus connected upon a last and thc-n drawing a further section of the upper to the last and securing it to the sole. Accordlng t0 the preferred method of practising the invention, a flange is produced on the heel of the upper and secured to and around one end of the insole and then these assembled parts are mounted, as a single unit, on and drawn to a last, as just described.

According to another feature of the invention, one or both of the ends of the upper are molded, shaped or formed to a shape corresponding to that of the last not only before the upper is mounted upon the last but also before the upper is secured to the insole.

In carrying out the invention in the particular manner hereinafter described in detail by way of illustration, the sides of the upper at the heel end of the shoe are molded or shaped and the heel flange formed over metal or metalfaced forms, which may be heated and then the flange is permanently and firmly secured to and around the heel of the insole, all as one continuous operation, after which the last is inserted within the upper and insole unit and then the remainder of the upper is drawn to the last and secured to the insole, for example, in a manner similar to that now carried on in A conveniently be seized by grippers such as those commonly used in hand lasting or in pulling over machines.

According to one feature of the invention, after the last has been inserted within the assembled upper and sole, a portion of the margin of the sole is accurately positioned in predetermined relation to the edge of the last and then the upper is drawn to the last and secured to the sole.

While the invention preferably comprises all of the steps herein described, yet obviously many of the advantages of the invention will be obtained even although some of1 the steps are modified, omitted or replaced by other corresponding steps now commonly performed. It will be understood,therefore, that the inventioncomprises not only the complete method herein described but also various novel and useful steps or combinations of steps in the art of making shoes also the article of manufacture, all of which, as well as the scope of the invention, will be defined in the appended claims.

The preferred mode of practicing the invention will now be described in detail in connection with the accompanying drawings, whereinig. 1 is a side elevation, partly in section, of the toe of a partially molded upper and certain portions of an apparatus which may be conveniently used in shaping it;

Fig. 3 is a similar view of the heel of the upper and of a-portion of apparatus which may be used in molding and Hanging it;

Fig. 7 is a. view similar to Fig. 6, showing the stage in the manufactureof the shoe when the fianging of the heel is substatially completed and the insole is about to be ap-V plied thereto;

Fig. 8 is a similar view showing the insole secured to the heel fiange by an adhesive;

Fig. 9 is a similar view showing the step of inserting lasting tacks for further securing the flange to the insole;

Fig. 10 is a similar view of the shoe after the last has been partially inserted;

Fig. 1l is a perspective view of the shoe as it is being pulled over and toe lasted, and

Fig. l12 is a similar view of the shoe after these operations hme been completed.

ln carrying out the invention, there is provided, according to the illustrative method, an upper 2 which may comprise the usual elements, such as the leather, or perha-ps cloth, upper itself, including a toe cap 4, a lining 5 and toe and heel stifi'eners of any suitable type, the heel stifener being shown at 6 in Fig. 2. This upper may be cut more closely to its final size than is the customary practice. After the parts of the upper have been securedtogether, the toe is molded or formed to give it substantially the sha-pe of the last upon which the shoe is to beilargely manufactured. As a result of this operation, as herein illustrated, the marner mold or former l0, an outer mold or cooperating member 12, the two molds being movable both relatively to each other and also movable together with respect to a table 14. and a U-shaped clamp 16 between which the margin of the upper will be yieldingly held. As set forth in the prior patent just mentioned, the toe of the upper, particularly if a certain commonly used type of selfhardening toe stiffener is employed, will be softened by heat or moisture or both before the molding pressure is applied. The inner mold 10 having been drawn away from the l outer mold 12 and the clamping members 14 Fig.`2 is a perspective view of the complete upper after the toe has been molded;

and 16 having been sufficiently separated, the toe of the upper is inserted and properly located, by appropriate gages or otherwise, between the respective molds and clamping members. The latter are then relatively actuated t0 stretch the toe of. the upper and to give it approximately its final shape, as indicated in Fig. 1. After the upper has suiliciently set, the wedge 18 supporting the table 14-L is retracted slightly whereupon both molds are raised further relatively to the clamping members with the .result that the margin of the upper is gradually withdrawn from these members against frictional resistance and, being drawn over the inner lower edge of the member 16, the margin of the upper isshaped as an upright flange 8 (Figs. 2 and 10).

The heel of the upper is next molded. As in the case of the toe, the heel is preferably formed substantially to the ,shape of the last upon which the shoe is to be manufactured but, as is elsewhere herein more fully explained, it is really overmolded to compensate for whatever reaction takes place. As shown in Fig. 3, 'the heel molding apparatus com rises an inner mold or form 20, the upper ace, or the whole of which, is of metal and which is preferably heated as by an electrical unit 22. Suitable mechanism, a portion of which only is shown, is provided for raisin and lowering the mold as required. o-operating with this inner mold is an outer mold 26 which is shown as sectional and provided with a. continuous. lining of leather or the like 28. Above the outer mold are wiper plates 30 for breaking down and shaping-'the heel flange. Preferably, also a neck presser 32 is provided to engage the upper preliminarily adjacent to als the lower edge of the heel stiffener, as shown i fdr example 1n Fig. 4, and to force the upper forwardly and to tilt theends of the heel stiffener upwardly in'the vicinity of the shank of the shoe. The inner mold is movable ,longitudinally relatively to the outer molding parts 26, 30, 32, thus facilitating the placing of the heel of the upper about the inner mold. The location ofthe edge of the upper with relation to the face of the mold 2() and laterally may be determined by the eye or by suitable gages, whereupon the upper is drawn to fit snugly about the mold, as shown in-F ig. '3. Thereafter, the mold 20 is moved relatively backward to the position indicated in Fig. 4 where the neck presser 32 is shown clamping the upper between itself and the lower portion of the face of the mold, thus, as just described, tilting the ends of the heel stiffener 6 and also the overlying upper materials and forming-a pocket to fit the ball of the heel of the wearer.

Then, they outer mold 26 is closed around the upper co-operating with the inner mold 20 tor shape the sides of itsheel. The wipers 30 are then moved inward, and preferably are moved inward and outward several times as indicated by the diagram D in 'Fig 6, to break down, iron and shape the inturned heel flange 38 and to produce a sharp break or angle between it and the sides of the heel.`

hen, the upper is allowed to remain under pressure within the mold until it` has become sufliciently set, whereupon the molds are seperated somewhat as shown in Fig. 7 the inner mold 20 being lowered away from the fiange 38 a distance somewhat vgreater than the thickness of an insole and the pressure on the outer mold 26 being relaxed. However, the mold 20 may be moved also slightly forward if desired. lIt is believed it thereto'. f in Fig. 7 with a sewing ip or rib and with stifi'eners -to shoe bottoms.

that the upper will be sustained b the outer mold in the position shown in ig. 7 but other mechanical means or the hand of the operator mayl 'also assist in thus sustainingit. 'Y

The next step in the process is to locate the insole 40 within` the upper-and to secure The insole, rovided vas shown an adhesive 42 upon its upper face, is now slid into place between the lower face of the.

consolidate the insole firmly against the fiange 38, the pressure being resisted by the wipers 30. Instead of or in addition to the adhesive 42, tacks 44 may be driven through the heel fiange ..38 and the insole 40 and clinched upon the metal facev of the mold 20. As shownv in Fig. 9, any suitable'tool such as an ordinar hand tacker 46 may be employed for this purpose. Before the tacks' are driven, the wipers 30 will be withdrawn sufficiently to expose the inner margin of the upper.

It is contemplated that, under some circumstances; it may be considered preferable to locate the heel of the insole upon the inner mold, somewhat as shown' in Fig. 8, before'the heel flange is broken down and then to shape and iron the flange over the insole during the initial heel molding operation. In that case,.the upper face of the mold 20 may be provided with spurs which are pressedinto the inner face of the in sole and which prevent displacement of the insoleJ durin the heel molding and Hanging operation. loreover, in such case, a thin edged metallic plate may be held upon the end of the insole during this'operation so as to present a rigid edge over which'to form the sharp break or bend in the "upper, this plate .being` withdrawn before the'adhesive 42 is applied or the tacks 44 are driven.

In t-hemolding or shaping of the upper, both at the toe and heel, it will usuallybe preferable to over mold the materials, that is to say, the curves of the molds 10, 20 and of their complemental parts will be exaggerated, thus compensating for the elasticity or reaction ofthe upper materials after they are removed from lthe molds. Indeed, lobviously, if when the upper-is applied to the last, it is thus overmolded, ,less pull thereon Vis required to shape it finally to the lastthan would be the case if the upper were undermolded. On the other hand, even if the materials do react considerably after thay have been removed from the molds, yet, because they have once been stretched or overmolded as described, they can be more easily drawn down to the last again.

The shoe is now ready forsuch further pulling over and lasting as may be desired. A last 48 of an ordinary or suitable type is 'inserted Within the'assembled upper and insoleeither by being passed through the topofthe shoe or, the insole being bent back at the toe, through the bottom thereof. The heel end of the last. is forced well back into ythev molded heel of the upper and against the ficient to state that the machine employed may be generallyof a type now in use and 4 clamps` 54, toe and sidegrippers or pincers 56, tack blocks 58, tack drivers 60 and toe; wipers 61. Preferably, the machine will beprovided also with means for correctly locat ing the forepart of the insole with relation to the edge contour of the' last and also with means for holding down the margin of the insole as the upper is drawn to the last. In Fig. 11, this gaging and holding means is shown as fingers 62each provided with an extension 644` adapted to bear against and aline both the edge of the insole and the edge of the last at its bottom. The fingers are provided. also with lugs or shoulders 66 constructed and arranged to press down upon the feather of the insole outside the sewing rib, These fingers-may be supported in the machine and actuated in any known or suitable manner so as to be withdrawn'from engagement with the insole after the upper has been drawn to the last so as not tol interfere with the mechanisms which carry the upper over and secure it to the insole.

The last 48 having been inserted within the assembled upper and insole and the insole having been laid down upon. the bottom of the last, the shoe' is presented to thepulling over and toe lasting mechanism, the flange 8 being entered between the jaws of the grippers 56 and theinsole being'located on the last by the fingers 62. Because of the preliminary stretching and molding to which the upper has been subjected, very little stress is required to draw the forepart of ,Y the upper snugly to the surface of the last.l

After Athis step. has been accomplished through the action of grippers 56, the fingers 62 are withdrawn and the wiping and tack driving mechanisms are actuated to force the upper over the feather of the insole and into the angle between it and the sewing rib. The upper may then be secured in this position by tacks 68 or by both tacks anda toe binder such as thewire 70. This operation may be erformed as fully described -in said Patent o. 1,135,949. Both the toe and heel lasting having now been completed, the lsides may also be lasted, if desired, by hand or by machine,` although even for a welt shoe, it is contemplated that some shoe manufacturers vwill consider it unnecessary to side last a shoe made according to the above described process except as such lasting iseft'ected durin the attachment of .the welt.

from this point on, the manufacture of the shoe may be completed in any known or suitable manner, the bottom. including both sole and `heel being applied and secured to the lasted shoe and then iinished as may be desired.

While I have thus described in detail one method of practising my invention, it should be understood that my invention is not limited in its broader aspects to the inclusion of every step described because many of the advantages of the invention can be secured by carrying out a portion only of the several steps of the complete process.
